To all whom tmay concern:

n a LLBERT r- "m- Be it know th t I, i X F Sill ZING, a subject "of the King of Great Britain,

and a resident of the city, county, and State ofNew York, have invented certain nevfand useful Improvements in Transom- Pivots, of which the following is a specification.

My invention relates to pivots, and more particularly to pivots such as are used for pivotally mounting objects, especially window sashes and transom or fan lights.

an object of the invention isto provide a pivot which shall be simple and cheap in construction and durable and eilicient in operation.

A further object of the invention is to provide a pivot which may be easily and quickly put into operative position and which when in operative position will present a continuous surface adapted to conform with the surface of the adjacent woodwork.

It also an object of the invention to provide a pivot which shall be proof against the passage of light, air, dust, storms, etc.

These and other objects of the invention will in part be obvious and in part made clear from the following description.

My invention consists in the novel parts,

improvements, and features of construction herein shown and described.

The accompanylng drawlngs, which are referred to herein and form a part hereof,

' illustrate one embodiment of the invention together with a certain modification there of, the same serving in connection with the description herein to explain the principles thereof.

Of the drawings, Figure 1 is a face view of one member of a pivot constructed in ac cordance with the invention; Fig. 2 is a similar view of the other member; Figs. 3 and 4 are similar views illustrating a modification; Fig. 5 is a side elevation of same with the parts assembled; Fig. 6 is a vertical central sectional view of the same; Fig. 7 is a side elevation of a transom door frame and a fan light mounted therein with the form of the device illustrated in Figs. 1 and 2, the parts at one side being in vertical section to more clearly illustrate the construction; Fig. 8 is a vertical sectionon the line 88 of Fig. 7, the parts being shown in a different position; F in. 9 is a similar view with the fan light and pivot removed; and Fig. 10 is an end View of A pivot made in accordance with my in ventioncomprises a pair of pivot members having oblong body portions terminating in complementary wings or extensions, the said body portions having means adapted to form a pivotal connection between the members and also having provision for securing the members in position. In accord ance with one feature of the invention, the opposite edges of the pivot members are formed on parallel lines, and one edge of each of the. wings forms an extension of the corresponding edge of the body portion. In accordance with another feature of the invention, each of said wings has a thickness corresponding to the combined thicknesses of the two body portions of the pivot, whereby when the members are assembled and in their closed relation a structure is provided, the opposite longitudinal edges of which present practically continuous parallel. surfaces. In accordance with one feature of the invention, the body portions are provided with one or more projections and recesses concentrically arranged with relation to the pivotal axis of the members, the same serving to span the space between the thickened wings or extensions so as to seal the joint between the two members, thereby preventing the passage of light, air, dust, rain, etc., through the same. In accordance with another feature of the invention, the body portions as well as the ex tensions thereof serve as a means for securing the members in place. These and other features of the invention. will be more particularly set forth in the following descrip tion.

Referring in detail to the particular embodiments of the invention illustrated in the drawings, andfirst to the form of the device shown in Figs. 1 and 2, A, B represent the body portions of the two members of the device. Asshown, the opposite edges of each of these body portions are formed in straight parallel lines. Suitable pivotal connect-ion between the members is provided, the same consisting, in the particular embodiment of the invention illustrated, of the stud 5 of the member 13 which turns in the corresponding aperture 6 of the member A, and which stud may be of any desired length to provide against shrinkage of the woodin which the pivot members may be placed.

Complementary wings 7 8, and 9, 10 extend from the members A and B, respectively, one edge of each wing preferably forming an extension of the coresponding edge of the body portion from which said wing or extension projects. Each of the wings or extensions 7, 8, 9, and 10 is preferably made of athickness substantially equal to the combined thicknesses of the body portions of the members A and B, so that when the members are assembled and in their closed relation, the opposite longitudinal edges of the structure thereby formed will present practically continuous parallel surfaces, as indicated in dotted lines in Fig. 1.

An important feature of the invention consists in the provision of means for spanning the space between the wings or extensio ns when the members are in their closed relation so as to seal the joint between the two members. As shown in Figs. 1 and 2, this is done by providing the circular recess 14 of the member A, which is arranged concentrically with relation to the stud 5 and in which recess loosely fits the projection 15 of the member B.

hen the device is used with a door frame and fan light, for instance, it may be desirable that the fan light shall be allowed to open to its fullest extent, as shown in Fig. 8. In this case the moving member of the pivot will 'be in a position at right angles to the stationary member. To permit of such movement, the longitudinal distance between the innermost extremities of the wings or thickened extensions of each of the members must be at least equal to the width of the body portion of its coiiperating member; and to effectively span this space, the circular recess 14 of the member A and its corresponding projection 15 of the member B shall each have a diameter greater than the width of the members. It will be noted that in this case the center part of the pivot will not be properly sealed by the recess 14: and projection 15, as the opening formed by the intersection of the recess with the opposite edges of the body portion of the member A may be somewhat greater than the width of the pivot 5. In order to span these central openings, a second smaller concentric circular recess 16 and projection 17 may be provided, the recess preferably being formed on the member A and the projection on the member B, as shown.

An important feature of the invention is the great strength of the pivot members A and B, and this is furnished by giving the body portion of each member a longitudinal extentwh-ich ismaterially greater than its widthand by eonnectingthe wings or extensions to the bodyportio-ns on oblique linessoas to-aflord elongated lines of connew be ee he ex s ns e d. he bo -y portion as well ast'o permit the proper opening and closing or pivotal movements of the members with relation to each other. Perferably, the body portion is so extended that it may serve as a means for securing the members in place in addition to the wings, thereby relieving the strain on the connection between the wings and the body portion.

Any suitable means may be employed for securing the members in place. As shown, holes are provided for the reception of screws, said holes being preferably so disposed as not to diminish the strength of the members. They may be arranged within the circular recesses or projections, as shown,

for example, in Fig. 1, or they may be arranged upon the circular recesses or projections as indicated in Fig. 2. Preferably, also, each of the wings is provided with securing means, as for instance, the hole for the reception of the screw.

An important feature of the invention is found in the shape of one of the wings or extensions whereby the setting of the pivot is facilitated. In accordance with this feature, one of the wings, and preferably one of the wings of that member which is to be relatively fixed, is extended or so formed that when the member has been fitted in place in the door or window frame, the weight of the sash or fan light to which the other member is secured will tendto hold the pivot in its fitted position. As

shown, the upper wing or extension 9 of.

the member B is extended upwardly along its inner vertical edge so as to provide a downwardly and outwardly inclined upper end. By reason of this construction the pivot with one of its members attached to the sash or fan light and the other member loosely engaged therewith may he slipped in place in the recess provided fort-he relatively fixed member in the door frame and removed, as required, for proper fitting with ease and with out liability of the unattached sash or fan light dropping out. In the case of a fan light, for instance, at each end of the light a pivot member may be secured in position, as indicated at A in Fig. 10, suitable beads 18 and 19, preferably of the same width and thickness as the wings of the pivot member, being secured in line with said wings. The proper places for the other members B of the pivots being marked upon the door frame, as nearly as may be, beads 21 and 22 are secured in place temporarily or otherwise, as shown in Fig. 9, the upper bead members 21 being shaped at their lower ends to correspond to the inclined ends of the upper wings or extensions of the pivot members B. The pivot members Bmay then beslipped in place upon the members A and the fan light placed in position in the door frame. Asthe pivotal connections between the members come in linewith "the inner edge of thelower beads 22, the weight of the fan light will tend to cause it to fall out of its place. The upper tapering edges of the ends of the wings or extensions of the members B will nreveiiit this, however, by contact with the correspondingly shaped ends of the beads 21. After any alterations have been noted, the parts may be removed and the alterations made; and if desired, the fitting operation may be repeated with out danger of the fan light falling out of place when temporarily inserted. After the fitting is completed, the members B may be secured in place by turning the fan light into the horizontal position, as indicated in The embodiment of the invention illus trated in 3, l, 5, and 6 shows a modification which is particularly suitable for use with transom windows or fan lights. It is not always desirable that a fan light should be capable of being opened to the fullest extent so that the window shall be in a position at right angles to the casing or frame but rather is it suitable that the window should open to a more limited extent. In such a case the longitudinal distance be: tween the innermost extremities of the thickened wings or extensions 7 8, and 9',10' may be somewhat less than the width of the body portions of the members, in which case the diameter of the circular recess 16 of one member and the diameter of its corresponding projection 1'? may each be less than the width of the members without permitting the aassago of light, air, dust, storms, etc., through the pivot, a second recess or projection being therefore unnecessary. y

it will be understood that where it is not desired to make special provision for sealing the pivot against the passage of light, air, etc, the projections and recesses may be omitted.

It will be seen that by reason of the construction shown and described a pivot which is of maximum strength at all points is provided and at the same time the construction is simple and neat in appearance and easily applied. in accordance with the preferred construction also, a aivot is provided which is perfectly sealed from the passage of air or dust, etc.

A special advantage of the construction resides in the fact that when in the closed position, it presents at its visible edges a surface wh ch is smooth and C011l3111110US and forms or may form a practical continuation of the woodwork in which it is lfitted, and particularly of the beads which are commonly used in fitting pivot window sashes and fan lights, the opposite edges of the members being rounded, as indicated in the drawings to correspond with the rounded edges (if the beads or moldings. Another that itinay be formed of simple castings i which requirelittle or no fittin It is to be understood that my inventionin its broader aspectsis not limited to the precise construction shown nor to any particular construction by which the invention has been or maybe carried into effect, as many changes may be made in the details of the parts without departing from the main principles of the invention and without sacrificing its chief advantages.
